What is a potential risk associated with long-term catheter use?

Long-term catheter use poses a significant risk for the development of infections, particularly urinary tract infections (UTIs) and catheter-associated urinary tract infections (CAUTIs). The introduction of a foreign object, such as a catheter, into the urinary system can disrupt the normal flora and create an environment conducive to bacterial growth. Additionally, biofilm can form on the surface of the catheter, further increasing the risk of infection as bacteria can adhere to and proliferate on these surfaces.

Preventive measures, such as maintaining sterile techniques during insertion, ensuring proper catheter care, and timely removal when no longer necessary, are critical in minimizing these risks. In contrast, while conditions like high blood pressure, dehydration, and hypertension may be concerns in a clinical setting, they are not directly associated with catheter use. Therefore, the potential for infection is recognized as a primary concern with long-term catheterization.
